" Be it known that I, PETERMIGGETT, of

Hoosick Falls, inthe county of Rensselaer and State of New York, haveinvented a new and useful Shuttle-Guard for Preventing Shuttles BeingThrown Out of `Power- Looms; and I do hereby declare that the followingis a full, clear, and exact descrip#` tion of the same, reference beinghad to the accompanying drawings, forming part of this specification, inWhich.-d

Figure l, is a front elevation, full size, of the shuttle guard `for theleft hand shuttle i box. v Fig. 2, is a top view of the same, and

Fig. 3, a view looking from the center of the loom toward the shuttlebox. Fig. t, is a diagram on a small scale, showing the position of theguard over the shuttle box.

Similar letters of reference indicate cor responding parts in theseveral figures. In power loom weaving, frequent interruptions arecaused by the shuttles accidentally flying from the loom. Theseaccidents cause much loss of time, injury to the fabric, and in manycases, injury toy the mechanism of the loom.` In the most improvedlooms, which run at the highest speeds, the shuttle is driven with suchforethat, if it iiies `from the loom, it is capable of inflicting` very`ing opening for the shuttle to enter.

serious, and even very fatal, injury, on the attendants, Whose duty itis to` superintend their operation.

The object of this invention is to prevent the liability to theoccurrence of these acci dents.

To enable those skilled in the art to make and use my invention,.I willproceed to describe its construction and operation.

A, is a casting of iro-n, or other metal, which is lintended to bebolted to the back of the shuttle box. It is of such shape as to formthe top and front side of the entrance to the shuttle box and present aflirts inside shape is represented in red lines in Figs. l, and 2. Onits front side, are two lugs, a, a, whichwith a pin, el, insertedthrough them, form guides for the shuttle binder.

B, is a spring, made of steel plate, and secured to the casting, A, by abolt, b, which serves at the same time to attach the casting to theshuttle box. This spring is slightly arched, and extends over theshuttle box toward the end oit' the lay. It is curled at the end to forma tubular bearing to receive the smallaxle, c, of tworollers, C, @whichmay be of metal, wood, or leather. This axle turns freely, and therollers are tightly secured to it. The rollers occupy such a positionthat when the shuttle is in the box, they stand .just over that end ofit Which is .nearestthe warp, as shown in Fig. 4, and at such a height,that the. shuttle is capable of passing under them without touching.

The principal cause ofthe shuttle ying from the loom, is the end 4nextthe `warp rising asit leaves the box. This is eii`ectually prevented byemploying the guard described for if the end rises, it comes in contactwith the rollers, and consequently is pressed down to its place, and-guided straight out of the box. Looms to which this shuttle guard hasbeen applied have turned off one tenth more work than other looms ofprecisely similar construction Without it, having given much lesstrouble to the weaver, and to the machinist, whose duty it has been torepair them.

It will be obvious that, as compared with the ordinary cleat in theinternal back edge of the race, plate cover over the top whether rigidor elastic, or bar at the backend of the race sustaining the pickerguide rod which i rod in part ordinarily serves to guide the shuttle, myconstruction and arrangement of guard serves more certainly andeffectively to guide the shuttle straight and restrain it from flyingout by preventing its end next the Warp rising on leaving the box, asthe small surface `exposed to friction on the shuttle touching therollers, the easy yield or turning of the rollers and the manner inwhich they are hung on a spring bar running lengthwise with the travelof the shuttle, all combined, serve to admit of the guard-that is therollers-being adjusted in closer proximity to the shuttleL withoutdetriment to the shuttle in striking, or serous wear of the shuttle,than would be safe or practicable With a fixed cleat or plate coverguide, and insures by the arrangement of the rollersone on either sideof the center line of the shuttlethe shuttle from turning and enteringthe opposite box edgewise, and thus it is that my .box guard enables meto run the loom quicker and the shuttle with greater precision, safetyand less wear or friction.

What I claim as new and useful and desire to secure by Letters Patentis- The shuttle box-guard constructed sub stantially as speciiied ofrollers (C C) on either side of the center longitudinal line of theshuttle and projecting from aspring bar or holder (B) down into the boxas shWn and described, whereby the shuttle is more effectuallyrestrained from rising at the end next the Warp on leaving the box, thuspreventing the shuttle from flying out of the loom or more trulyinclosing it to run in its course7 friction is diminished, the vshuttle10 less exposed to injury or Wear and kept from turning or enteringtheopposite box edge- Wise, as herein set forth.
